This format should be used for the first post of a thread for any individual map submission. You should have this template (In your first post):

MAP NAME: [Map title]MAP NUMBER: [Map number, like "map01"]Progress*: [How close are you to done?]Description: [Description of your map, what is the purpose, theme, etc. What do you want to achieve with your map?]Screenshots: [Screenshots, spoilered plz]Download: [Download link to your map, sendspace, drd team, or another reliable and lasting link is preferable]

Feedback on each map will be given in their respective threads. The mapper should update his map whenever a major change is made (update the download link with your update). Post a changelog of what you did since the last revision of your map as well.

Once the map is done, anyone is free to work on it (if the author allows this) if it needs touching up or fixes. Just post if you plan on making a change, even a tiny one, so that no one else starts working on it at the very same time you decide to do something on it, once you are done, upload your "update" and include a changelog of what you did.
